Newly discovered bacteria turns matter into 24-karat gold

Must read

A bacterium has been found that supports very high levels of toxicity and can convert natural compounds into 24-carat gold. 

The process is on display in an art gallery to show the relationship between ancient alchemy and modern microbiology.

A team from the University of Michigan discovered a bacterium, Cupriavidus metallidurans, that withstands very high levels of toxicity and can convert natural compounds into 24-karat gold. The process is known as microbial alchemy.

The team was led by Kazem Kashefi, professor of mycobiology and molecular genetics, and Adam Brown, professor of electronic art. Together they combined the research with an art installation called The Great Work of the Metal Lover, which features a combination of biotechnology, art and alchemy. The sculpture is a portable laboratory that produces a gold bar in front of the audience.
This process is time consuming and on a large scale would be too costly. For this reason, Brown preferred that the work be used to “ask questions about greed, economics and the impact on the environment, focusing on the ethics related to the science and engineering of nature.”
“Art has the ability to ask about the impact of science on the world, and The Great Work of the Metal Lover speaks directly to these scientific concerns,” said Brown.

  1. Very amusing – bacteria with teeny tiny particle accelerators inside of them! That's the only real way you can create gold. You'd have to feed them each a tiny dot of lead, and then hook them up to vast quantities of electricity to power the teeny tiny accelerators (and, somehow, keep the bacteria from frying) – and you'd produce a tiny dot of gold. Yes, I'd pay to see that.

  2. Me too, I love the way you described it too. It comes across as an affectionate admiration for the little guys, which is a mutual appreciation at my end too!
